The 24-year-old Danish songwriter IAMJJ wrestles with the biggest themes in his heartfelt songs. And he dares to name the largest of names as sources of inspiration: Nick Cave and Leonard Cohen from the world of music, Damien Hirst and Tal R from the world of visual arts. The melancholy you hear in IAMJJ’s music is striking, and it’s hard to believe that he’s Danish and only 24. But he is.
